Precision Tooling & Regularly Calibrated Accuracy
For manufacturing we use the best technically designed CNC turning centers, CNC grinders, and Super-finishing machines — both Indian and imported.
Machine accuracies are regularly calibrated so that each and every race is machined to its exact geometrical accuracies, ground, and surface finished to achieve very low noise levels.
Bearings are assembled after proper gauging and well-designed fixtures to achieve high levels of running accuracy. Before packing, each and every bearing is inspected, and comprehensive records are maintained to track its historical traceability in case of any customer query.
Our 6-Stage Manufacturing Workflow
From prime alloy steel to finished, certified precision bearings.
SAE 52100 Steel Sourcing & Inward Testing
Every raw material batch of SAE 52100 / 100Cr6 alloy steel is inspected for chemical composition, inclusion rating, and grain uniformity prior to production.
High-Precision CNC Turning Centers
Technically designed CNC turning centers machine inner and outer bearing rings to strict geometrical tolerances with high repeatability and zero distortion.
Controlled Atmosphere Heat Treatment
Rings undergo specialized quenching and tempering to achieve a homogeneous martensitic microstructure with an optimal core and raceway hardness of 60–64 HRC.
Precision CNC Grinding & Super-Finishing
Both Indian and imported CNC grinders and super-finishing honing machines produce mirror-smooth raceways, eliminating microscopic peaks and ensuring whisper-quiet running.
Fixture Assembly & Electronic Gauging
Bearings are assembled in clean room conditions after rigorous dimensional matching with precision ball/roller grades and specially designed assembly fixtures.
100% Inspection, Traceability & Preservation Packing
Every individual bearing undergoes acoustic vibration testing and visual inspection. Detailed batch records are maintained for full history traceability before rust-proof sealing.
Historical Records & Zero-Defect Commitment
Quality is not just a final checkpoint at Darshak Bearing — it is integrated into every cutting, grinding, and assembly motion.
- Pre-Packing Inspection: 100% check of running clearance, radial/axial play, and noise frequency.
- Batch Traceability: Complete logging of heat treatment numbers, raw material heats, and machine operator logs.
- Moisture-Proof Packaging: VCI anti-rust coating with heat-sealed poly wraps to guarantee zero corrosion during maritime export and domestic transit.
